At 03:33:46 UT, the Swift Burst Alert Telescope (BAT) triggered and
located GRB 240606 ***A*** (trigger=1235109). Swift slewed immediately to the burst.
The BAT on-board calculated location is
RA, Dec 12.125, -19.747 which is
RA(J2000) = 00h 48m 30s
Dec(J2000) = -19d 44' 49"
with an uncertainty of 3 arcmin (radius, 90% containment, including
systematic uncertainty). The BAT light curve showed a [**double-peaked**]
structure with a duration of about TTT sec. The peak count rate
was ~1390 counts/sec (15-350 keV), at ~6 sec after the trigger.
